Module eui48

IEEE 48-bit EUI (MAC address) logic.

Supports numerous MAC string formats including Cisco's triple hextet as well as bare MACs containing no delimiters.

Classes

mac_eui48
A standard IEEE EUI-48 dialect class.

mac_unix
A UNIX-style MAC address dialect class.

mac_cisco
A Cisco 'triple hextet' MAC address dialect class.

mac_bare
A bare (no delimiters) MAC address dialect class.

mac_pgsql
A PostgreSQL style (2 x 24-bit words) MAC address dialect class.

DEFAULT_DIALECT
A standard IEEE EUI-48 dialect class.

Functions

valid_str(addr)
Returns: True if MAC address string is valid, False otherwise.

str_to_int(addr)
Returns: An unsigned integer that is equivalent to value represented by EUI-48/MAC string address formatted according to the dialect settings.

int_to_str(int_val, dialect=None)
Returns: An IEEE EUI-48 (MAC) address string that is equivalent to unsigned integer formatted according to the dialect settings.

int_to_packed(int_val)
Returns: a packed string that is equivalent to value represented by an unsigned integer.

packed_to_int(packed_int)
Returns: An unsigned integer equivalent to value of network address represented by packed binary string.

valid_str(addr)

Parameters:

addr - An IEEE EUI-48 (MAC) address in string form.

Returns:

True if MAC address string is valid, False otherwise.

str_to_int(addr)

Parameters:

addr - An IEEE EUI-48 (MAC) address in string form.

Returns:

An unsigned integer that is equivalent to value represented by EUI-48/MAC string address formatted according to the dialect settings.

int_to_str(int_val, dialect=None)

Parameters:

int_val - An unsigned integer.
dialect - (optional) a Python class defining formatting options.

Returns:

An IEEE EUI-48 (MAC) address string that is equivalent to unsigned integer formatted according to the dialect settings.

int_to_packed(int_val)

Parameters:

int_val - the integer to be packed.

Returns:

a packed string that is equivalent to value represented by an unsigned integer.

packed_to_int(packed_int)

Parameters:

packed_int - a packed string containing an unsigned integer. It is assumed that string is packed in network byte order.

Returns:

An unsigned integer equivalent to value of network address represented by packed binary string.
